Abstract

A printed wiring board has a first conductive layer including a second electrode group bonded to a first electrode group of a flexible printed circuit board, and a second conductive layer, and a plane including the second conductive layer includes a first region including a reference region set in a bonded portion, a second region via a first boundary, and a third region via a second boundary, and a first boundary portion is positioned within a range of 0.5 times or more and 5 times or less a length of a short side of four sides in a prescribed direction, and a second boundary portion is positioned within a range of 0.5 times or more and 5 times or less the length of the short in a prescribed direction, and a density of the second conductive layer in the first region is higher than that in the second region.
